Find out what the International System of Units (SI) is and why we need it for global trade and quality infrastructure. The director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD, tells us about the historical development of the International System of Units (SI). This is the first in the series of 11 short films produced by the European Association of National Metrology Institutes (EURAMET) aimed at the promotion of the International System of Units and its forthcoming redefinition.

The director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD, explains how the International System of Units (SI) was established. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

Find out why it was necessary to change the definition of the kilogram and what are the drawbacks to the current definitions of the International System of Units (SI), as viewed by the director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

Why do we need the redefinition of the International System of Units (SI)? The director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD, speaks about this in the following video. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

How will the International System of Units (SI) be redefined? The answer to this question is given in the following video by the director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

The International System of Units (SI) is expected to be redefined in November 2018. One of the units which is going to be redefined is the kilogramme. The director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD, speaks about this in the following video. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

In the next short movie find out what are the benefits of a redefined SI? The director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD, emphasis the advantage of using natural constants in new SI definitions. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

Find out whether the change in definitions in the International System of Units (SI) will have an impact on everyday life, but also on calibration in laboratories… A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

The revised SI is also called ‘quantum SI’. Why and how counting of atoms is involved is explained by director of the Consultative Committee for the International Units and German National Metrology Institute (PTB), Joachim Ullrich, PhD. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

The redefined SI is also called the quantum SI. But what is hidden behind the idea of the 2nd quantum revolution? Joachim Ullrich, President of the Consultative Committee for Units and Germany’s National Measurement Institute (PTB), gives a short introduction to this fundamental development. A series of short films about the International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).

Currently, everybody is talking about quantum technology. How does the revised SI support the development of quantum technology? This is explained by Joachim Ullrich, President of the Consultative Committee for Units and Germany’s National Measurement Institute (PTB). A series of short films about the  International System of Units (SI) was produced and distributed by the European Association of National Metrology Institutes (EURAMET).
